SPECIFICATION forming part of Letters Patent No. 766,961, dated August9, 1904.

Application filed December la, 1903. Serial No. 185,182. (No model.)

To all whomV zit may concern:

Be it known that 1', CHARLES WV. MORRIS, a citizen of the United States,residing at Peoria, in the county of Peoria and State of Illinois, haveinvented certain new and useful Improvements in Hose-Oouplings; and I dohereby declare that the following is a full, clear, and exactdescription `of the invention, which will enable others skilled in theart to which it appertains to make and use the same.

This invention relates to a new coupling means for use on hose-pipes andthe like, but pertains more particularly to the hose connection betweenlocomotives and their tenders and between railway-cars.

The object of the invention is to provide a new form of hose-couplingthat will be equally adapted to any-sized fitting found on any pipe orhose, so that a connection can always be made without the least delay orunnecessary work.

In the accompanying drawings, Figure l is an elevation of a portion of alocomotive and its tender, showing a hose connection between the two asusually employed, showing my attachment thereon. Fig. 2 is a view of myentire coupling'. Fig. 3 is an end view of a clamp thereof. Fig. 4: is asectional view of the said clamp viewed the same as Fig. 3. Fig. 5 is asectional view of a portion of a hosefitting, showing my attachmentthereto.

A indicates the supply-pipe connected to the engine, and B indicates thehose leading to the tender or cars. Between these two pipes my improveddevice is located and which consists of a reducer O, having at one end aprojection D for entering the iitting E of the supply-pipe A. Near theopposite end of the portion O is a faced liange F for taking a wrench,and at the eXtreme end are screw-threads (i, by which the reducer may beattached to a fitting H of the hose B. Also at about midway ef thereducer are threads I, surrounded by a clip composed of the portions J,internally threaded to correspond. Between the eX- tremities of saidportions J are secured curved arms K by means of bolts L. Said arms Kextend forward and each terminates in a clip portion M, clamped aroundthe end of the pipe A by means of screws N.

In assembling the parts the reducer is connected into the fitting H ofthe hose B, and its reduced projection D is entered into'the opening inthe fitting E of the pipe. Then the clip ends M are placed over the pipeA and tightly clamped by the thumb-screws N. Itis only necessary now toplace a wrench upon the faced portion F, and by turning the same towardthe right, is customary, the entire portion O is worked through thethreaded clip portions J, thereby tightly forcing the shoulder of thesaid portion O against the fitting E, the arms K and their clip portionshaving previously been placed onC in the manner described. It isnecessary to provide some sort of swiveling connection, of course, topermit the portion O to be turned without loosening its connection withthe hose-pipe, and this swivel may be within the fitting H; but l havenot illustrated it, as it forms no part of my invention, but must ofcourse be provided, as will be obvious.

The purpose of employing the reducer O between the littings E and H,which' fittings are usually connected together in common practice, isthat these said iittings are rarely of a uniform size, it being oftenthe case that one of them is either too large or too small to connectwith the other, and often much time and annoyance results in iinallyfinding some means by which they may be connected in a water-tightmanner. Having found the disadvantage in such a construction, it hascaused me to bring' about the device herein described. The fitting H onthe hose-pipe is usually of a fixed size, and therefore a reducer of aiixed size will always answer. However,the iitting E is variable insize, and consequently provision must be made for making' connectiontherewith. I have shown in Figs. 2 and 5 a brass washer O interposedbetween the fitting E and the shoulder of O. This washer is variable insize-that is to say, a number of different sizes may be kept on hand, sothatthe desired connection can always be made. In Fig. 2 it so happensthat the fitting E is of about the same size the reducer, and the washerO would not be necessary, and l. may not use said washer in such case,since the shoulder of C will make the required tight joint; but in Fig.

IOO

5 the fitting is much larger. Consequently a large washer is necessary.This closes the opening of said fitting, while a hole in said washerpermits entrance of the reduced portion D. It will be seen that in bothcases a closed and tight joint is made. A rubber gasket may also be usedin connection with the washers O, if desired, to insure properconnection should any of the faces become injured in such a way as toallow leakage. By providing the arms K and their clamping means thereducer C may be brought up as tight as desired, so that a perfect unionof the pipes must result. As a matter of factIdo not desire to confinemyself to any particular' construction in bringing out my device; but Ihave described and illustrated the form I prefer to use.

What I claim isl. A hose-pipe comprising the two portions to beconnected, one of which is of a fixed size and the other of a variablesize, a member interposed between the said portions to be connected, oneend of said member being screwed into one of said portions, the oppositeend being shouldered and having a reduced end merely entering theopposite portion, a gasket interposed between the shoulder of the memberand the portion into which the member is inserted, and a clamping devicerigidly secured to one of the portions and carrying screw-threads at theother into which the interposing member is adapted to be screwedsubstantially as described and shown.

2. A hose-coupling comprising two pipe portions to be connected, one ofwhich is of a fixed size and the other of variable size, of a memberinterposed between the said portions to be connected, one end of saidmember adapted to screw into the pipe portion of fixed size, the otherend adapted to be held in fixed relation to the other pipe portion, awasher interposed between the member and the pipe portion last abovedescribed, and means for screwing the member firmly against the pipeportion such means being independent of the immediately-adjoiningsurfaces or free ends of said member and pipe.

3. In a pipe-coupling of the character described, the two portionsconstituting the pipe to be connected, a` member interposed between suchportions vone end thereof being secured as by screw-threads in one ofthe portions, the opposite end having abutting relation with theopposite pipe portion, and means for maintaining such relation whichconsists of a yoke member secured to the pipe portion last described,and extending past the abutting part and screw-threaded at the extremitythereof, said member being likewise screwthreaded to engage with saidyoke.

4. In a coupling for hose-pipes, the pipes A and B, fittings E and Hcarried by the said pipes respectively, the member C interposed betweensaid fittings, one end of said member adapted to screw into the fittingH, the opposite end of said member arranged to enter and abut againstthe fitting E substantially as shown, a clamp composed of the arms Khaving the clip members M thereon to clamp to the pipe A, the clipmembers J to which the arms K are connected, the said members J and themember C being threaded to correspond as described, said member Cadapted to tightly abut against the fitting E by being screwed withinthe said clip members J as described.

5. In a coupling for hose-pipes, the combination of the pipes A and B,the fittings E and H therefor respectively, the member C interposedbetween the fittings, one end thereof being' screwed into H, theopposite end engaging with E as described and shown, the washer Cbetween the member and fitting E, the arms K secured to the pipe A, theclip members J carried by the arms K and internally threaded, the saidmember C being threaded at I to correspond with and engage the saidmember J all arranged substantially as herein described.

In testimony whereof I affix my signature in presence of two witnesses.
